MANURE-LOADER.

Specification of Letters Patent.

Patented Nov. 28, 1911..

Application filed July 18, 1910. Serial No. 572,567.

-MAN, a citizen of the United States, residing at Tampa, in the county of Marion and State of Kansas, have invented a new and useful Manure-Loader, of which the following is a specification.

This invention has relation to manure loaders and consists in the novel construction and arrangement of its parts as herein after shown and described.

The object of the invention is to provide a loader of the character indicated in the form of a structure having a frame pivotally mounted thereon and which carries a platform adapted to be swung from a horizontal position approximately at the surface of the ground to an approximate vertical position above the structure. A backing plate is hingedly mounted near the inner edge of the said platform and is adapted to swing as the platform is moved to its uppermost position and serves as a chute for directing the material carried by the platform from the said platform into the body of a wagon or other receptacle.

In the accompanying drawings :Figure 1 is a side elevation of the manure loader. Fig. 2 is a sectional View of the same. Fig. 3 is a side elevation of the loader showing the platform thereof in elevated posit-ion. Fig. 4 is a top plan view of the loader with parts broken away.

The loader includes a support which consists of runners 1 connected by cross beams 2, 3 and 4. Side arms 5 are pivotally connected with the runners of the support and have a platform 6 secured to their forward ends and adapted as the said arms 5 are swung (as will be explained) to move from a position at the surface of the ground beyond the ends of the runners 1 to a position approximately vertical above the said runners. Standards 7 are pivotally secured at their lower ends to the sides of the free end portions of the arms 5 and an apron 8 is attached to the said standards. The platform 6 is provided at one edge with a flange 9 which overlaps that edge portion of the apron 8 which is adjacent the ends of the standards 7 that are pivoted to the arms 5. Stop arms 10 are pivotally secured to the arms 5 and may be secured in adjusted positions with relation to the said arms 5. The free end portions of the stop arms 10 lie in the paths of movement of the standards 7 and are adapted as the arms 5 are swung in an upward direction to limit the swinging movement of the standards 7 and apron 8 with relation to the platform 6.

Beams 11 are pivoted at their'lower ends upon the cross beam 3 of the support and beams 12 are pivotally connected at their lower ends to the inner sides of the runners 1. A bar 13 is pivotally connected at one end with the upper ends of the beams 12 and is pivotally connected at its other end with the upper ends of the beams 11. A sheave pulley 14 is journaled for rotation at the upper end of the bar 13 as shown in Fig. 1. When however the parts of the loader are moved to dumping position, the positions of the ends-of the bar 13 reverse so that the pulley 14 is at the lowermost end as shown in Fig. 3. Links 15 are pivotally connected at their upper ends with the upper ends of the beams 12 and the lower end of the bar 13 and at their lower ends the said links 15 are pivotally connected with the arms 5. Pulley blocks 16 and 17 are mounted upon the cross beam2 and a draft cable 18 passes through the block 17 thence over the sheave pulley 14 thence down and through the block 16 thence up and is secured at one end to the upper end portion of the bar 13 or its attachments. A bridle cable 19 is attached at one end to the cross beam 4 and at its other end is connected with the free ends of the arms 5. A snatch cable 20 is connected at one end with the bridle cable 19 at a point intermediate the ends of the said cable 19.

In operation and when the apparatus is being loaded with material the parts are in the positions as shown in Fig. 1 of the drawings. When so positioned it will be seen that the platform 6 rests upon the surface of the ground and that the side of the apron 8 is against the forward edges of the links 15. Materialis deposited upon the platform 6 by means of a horse fork or other accumulating implement and when a sufiicient quantity of material has been deposited upon the said platform the cable 18 is drawn whereby it moves through the blocks 17, 16, and over the sheave pulley 14 and the free ends of the arms 5 are swung in an upward direction. Previous to this however the body of a wagon or other receptacle has been positioned upon the ground beyond the ends of the runners 1 opposite those ends at which the platform 6 appears in Fig. l of the drawing. As the cable 18 is drawn as above indicated it pulls the upper ends of the beams 11 and the upper end of the arm 13 in a rearward direction the upper ends of the said parts describing an arc. Through the bar 13 the upper ends of the beams 12 are cable 19 becomes taut and the free ends of the arms 5 are held in elevated position. During the upward movement of the arms 5 some of the material carried by the platform 6 will fall back upon the apron 8 and the said apron is swung in a downward direct-ion until the standards 7 come in contact with the stop arms 10. And, when the arms 5 have swung to the extent of their upward movement the parts are in the positions as shown in Fig. 3 of the drawings and the material may fall from the platform 6 down along the apron 8 and from the lower edge of the said apron into the wagon body or receptacle. By pitching the stop arms 10 at a desired angle with relation to the arms 5 and securing the same the angle of inclination of the apron 8 when at dumping position may be varied so that the said apron will cause the material to fall relatively near or comparatively remote from the ends of the runners 1.

' When it is desired to lower the free ends of the arms 5 so that the platform 6 may resume its position upon the surface of the ground the snatch cable 20 is drawn which will cause the bridle cable 19 to assume an angle and the free end portion of the arms 5 will be swung toward the opposite side of the vertical line above mentioned and thus the said arms may descend and assume the positions indicated in Fig. 1.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. A loader comprising a support, an arm pivoted to the support, a platform carried by said arm, a beam pivoted to the support, a second beam also pivoted to the support at a point out of pivotal alinement with the first mentioned beam, a bar pivoted atits ends to the ends of the said beams, a link pivotally connected with said bar and said arm, and a drawing cable 0peratively connected with said bar.

2. A loader comprising a support, an arm pivoted to the support, a platform carried by said arm, a pivotally mounted apron located at the inner edge of the platform, a beam pivoted upon the support, a second beam also pivoted to the support but at a point out of pivotal alinement with the first mentioned beam, a bar pivoted at its ends to the ends of the said beams, a link pivotally connected with said bar and said arm and at times adapted to serve as a support for said apron, a drawing cable operatively connected with said bar, and a stop adjustably mounted upon the arm and having an end spaced from the apron but located in the path .of movement of the same as i the parts of the loader assume dumping position.

In. testimonythat I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
